Edit: 1038. It appears that some trains on the High Wycombe line may be starting / finishing their journeys at Wembley Stadium station. However connections by public transport there are poor into Central London (and it won't be all trains anyway. It is STRONGLYRECOMMENDED that passengers follow the official advice and travel directly to West Ruislip for travel to railway stations along the High Wycombe line.

Edit: 1345. Most trains towards London (on the High Wycombe line) are currently stopping at South Ruislip to drop off for connections to the Central Line. Trains out of London however are still picking up at West Ruislip. It is clearly proving difficult to run all trains to time - many have extra stops, so allow plenty of time and expect delays.

Edit: 1630. The Central Line is currently suspended between Westbound between Marble Arch and a White City. Not good news for Chiltern Railways passengers trying to get to West Ruislip.

Options seem to be:

Northbound Bakerloo Line to Wembley Central and then a 10 minute walk to Wembley Stadium station or

From Bakers Street or Edgware Road (H&C) stations take the Hammersmith & City Line to Wood Lane. White City station is a 3 minute walk from there, from where the Central Line runs to West Ruislip. Allow at least an hour from Marylebone.

The day just got worse.

Edit: 1715. Unsurprisingly, the Central Line suspension between Marble Arch & White City is now both ways. Expected to last until 1900 but no guarantees on this.

Edit: 1745. It appears that a through service has now resumed on the Central Line. Severe delays are reported at present.

Edit: 1950. Central Line has improved. Now just 'Minor Delays' reported.

Email received at 1920 from Chiltern Railways re tomorrow morning:

"Dear Customer,

Marylebone station is closed due to a cable fire. Around 2 metres of signalling cable in the tunnel into the station has burned away meaning the signalling system is not working. Without signals we cannot safely run trains, so are not running to or from Marylebone until new cables are installed and tested. Engineers are on site however, disruption is expected and Marylebone will be closed into Monday morning and until further notice.

Final Edit: 2320. Marylebone is not expected to open in time for the Monday morning rush hour. An emergency timetable has been published for the Amersham line. The Wycome line version will hopefully be out in the next hour or so.
